Desiring to give a local interest to the exercises in his book, Dr. Strachan gave several examples from Canadian subjects. Thus a question is addition reads:-- "From Quebec to Montreal is 180 miles--from thence to Kingston 200--from thence to York 149--from thence to Niagara 78 miles--from thence to Detroit, 210. Required the distance from Quebec to Detroit. _Answer_--317 miles." Again a question in multiplication reads:-- "The distance from Quebec to Montreal is 180 miles, supposing the road 17 yards broad, how many square yards does it contain? _Answer_--5,385,600 yards." As to his diligence as a student, while yet a teacher. Dr. Fuller remarks:-- "The late Bishop said to me on one occasion: 'I had to study every night quite as hard as the boys; for I was not much in advance of the highest class in school. These and parochial duties demanded sixteen hours every day,--and yet these nine years were the happiest years of my life." REV. DR. STRACHAN'S CAREER AS A TEACHER. Having been appointed Minister at Cornwall in 1803, Dr. Fuller states that there he was:-- "Induced to resume his school, at the solicitation of the parents of those boys who had been in his school at Kingston, and of others, both in Lower and Upper Canada, who were desirous of placing their sons under a master so practical, wise and successful, as he had proved himself to be. Thus he commenced the school at Cornwall, which afterwards became so celebrated, and at which were educated the first men that Canada has produced, and of whom she may well be proud--such men as the late Sir J. B. Robinson, Judge Maclean, Sir J. B. Macaulay, Sir Allan MacNab, Judge Jones, Mr. Stanton, the Bethunes (Alexander, John and Donald), Sir James Stuart, and his brother Andrew Stuart, besides many others who have reflected credit on our country. "The Bishop had a great faculty for not only attaching his scholars to him, but also for inducing them to apply themselves most assiduously to their studies. He told me he made it a rule, during the time he kept school, to watch closely every new boy, and at the end of a fortnight, to note down in a book his estimate of the boys who had passed through his hands.
